  1. 1. Produktion av edamame : kvalitetsparametrar för odling och konsumtion

    University essay from SLU/Dept. of Plant Breeding (from 130101)

    Author : Sandra Golobov; [2022]
    Keywords : antinutritionella faktorer; Glycine max; gröna sojabönor; grönskörd; isoflavoner; kvalitet; omogna sojabönor;

    Abstract : Sojabönan är en de viktigaste grödorna och odlas över stora arealer globalt. Den odlas främst för sitt höga proteininnehåll och relativt höga oljeinnehåll och anses därav vara en oljegröda. Edamame eller vegetable soybean är gröna sojabönor som skördas vid mognadsstadie R6 då bönorna fyller ut baljan till 80–90 %. READ MORE

  3. 2. Tundra carbon cycling in relation to sea-ice decline in a warming Arctic

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Juliane Glinski; [2022]
    Keywords : sea-ice decline; warming Arctic; earlier growing season; arctic tundra; heterotrophic and autotrophic respiration; climate warming; Earth and Environmental Sciences;

    Abstract : We set out to investigate whether arctic tundra acted as a sink or source of carbon dioxide (CO2) between 1980-2014 and to relate changes in the net carbon balance to Arctic sea-ice decline. We want to understand how climate change and arctic warming influence arctic carbon cycling. READ MORE

  4. 3. Assessing annual forest phenology: a comparison of Unmanned Aerial Vehicle (UAV) and phenocamera datasets

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Shangharsha Thapa; [2020]
    Keywords : Geography; Ecosystem Analysis; Near-surface Remote Sensing; UAV; Phenocamera; Forest Phenology; Phenophase; Seasonality; NDVI; GCC; Geomatics; Earth and Environmental Sciences;

    Abstract : Near-surface remote sensing platforms such as Unmanned Aerial Vehicles (UAVs) and phenocameras appear to be potential platforms for keeping track of seasonal dynamics at a local scale. This research focusses on extracting time series of different vegetation indices (VIs) from both platforms, computing seasonality events from them and comparing the results against spectral sensor data.

  5. 4. Slaughter weight in relation to calving date : can area quality compensate for being born late?

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Sanna-Maja Breiman Wistbacka; [2020]
    Keywords : moose; slaughter weight; birth timing; area quality;

    Abstract : The interaction between wildlife and environmental properties such as climate, water and forage availability and competition is a fundamental part when studying wildlife. In ungulates, mortality rates and reproductive success are closely linked to body condition. READ MORE

  6. 5. Vegetation phenology derived using the plant phenology index and the normalized difference vegetation index for the Balkan peninsula, south-eastern Europe

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Aleksandra Ivanova; [2019]
    Keywords : physical geography; ecosystem analysis; phenology; vegetation; climate change; remote sensing; plant phenology index; PPI; timesat; Balkan peninsula; Earth and Environmental Sciences;

    Abstract : This study analyses the performance of the satellite derived Plant Phenology Index (PPI) against the Normalized Difference Vegetation Index (NDVI) for estimating start of season (SOS) and end of season (EOS) of vegetation growth in part of the Balkan Peninsula, Southeastern Europe (2000 – 2016). Results revealed that PPI and NDVI differ considerably; SOS and EOS may diverge by more than one month between the two indices. READ MORE
